Types: Exports and export assignments are not permitted in module augmentations.

Been trying to install and use Apexcharts inside a Typescript project, but keep getting this weird error.

[ ERROR ]  TypeScript: node_modules/apexcharts/types/apexcharts.d.ts:956:1
           Exports and export assignments are not permitted in module augmentations.

    L955:  declare module 'apexcharts' {
    L956:  	export = ApexCharts;
    L957:  }

I was trying to fix this, and I found a way to get away from this error, I am just not sure if this is a right fix.

@junedchhipa You are a library and need to export your types… Make it fully public.

src/app/components/apexchart/apexchart.component.ts(2,35): error TS2305: Module '"apexcharts"' has no exported member 'ApexAxisChartSeries'.
src/app/components/events/events.component.ts(117,43): error TS2345: Argument of type 'true' is not assignable to parameter of type 'EntityChanged'.```

Hey @junedchhipa, I think your fix is too simplistic as importing types like ApexAxisChartSeries is no longer possible.

A (very simplistic) use case for importing these types is:

import { ApexAxisChartSeries } from 'apexcharts';
const series: ApexAxisChartSeries = [{ name: "Name", data: [1, 2, 3, 4]}];

Exporting at least ApexAxisChartSeries would also allow you to properly type the series property here: https://github.com/apexcharts/react-apexcharts/blob/master/types/react-apexcharts.d.ts instead of just using Array<any>.
